Thanks for the info, Jane. I was really hoping to narrow it down to entries during certain time periods, and, although I'm mainly interested in things written by Jews, reading what gentiles wrote would also be useful to give us a sense of living conditions and views about Jews. But I can't get the search to work for me by date, and with over 7000 entries, going through each of them just isn't feasible.
